He studied piano and music theory for eight years with his teacher, Victoria Doval. He studied harmony and composition with Sebastian Piana for 2 years and Ofelia Carbajal for 3years. He studied Jazz Interpretation (big band) with Gerardo Chiarella for 3 years. He studied violin for one year, guitar for one year, trombone for three years with Rafael Toscano and saxophone for one year with J. C. Bozzo. By himself, he learned accordion and folkloric instruments. Marcelo studied piano and music theory at the Antiguo Conservatorio Beethoven, where he obtained a teaching certificate in 1979. At the age of 18, he began to play the baritone sax, showing a particular interest in the music of Serge Chaloff; inspired by John Coltrane, Albert Ayler and Ornette Coleman, he went on to learn tenor sax, then alto and finally soprano.

While studying harmony and composition under tango composer Sebastian Piana, he taught himself to play trumpet, trombone, tuba, violin, clarinet and other Latin American folk instruments. Since that time he has taught at several schools. In 1980 he taught music in both elementary and high schools, as well as at special education institutions. At the same time, he was hired as a saxophone and improvisation instructor at the Conservatorio Municipal Manuel de Falla Buenos Aires.

At 18, he began his career as a freelance musician, and went on to play and record with a wide range of artists and in many styles: The Bucky Arcella Trio, Manolo Yanes, Litto Nebbia,Fabiana Cantilo, Cuatro Vientos (sax quartet), LRA National Radio Orchestra (as a soloist), to name a few. In 1985 he met the guitar player Jorge Mancini, with whom he began to experiment with free improvisation and contemporary music; they were joined by the sax player Mariana Potenza and the percussionist Victor Da Cunha, together creating the "Grupo de Improvisacion Tercer Mundo" (Third World lmprovisation Group). Although he had been playing the quena, the accordion and other ethnic and percussion instruments alongside the standard ones for several years, his interest in folk music was further developed in 1988 when he performed and recorded with the pianist and composer Eduardo Lagos (a great innovator in Argentine folklore). He developed a truly personal view of improvised music when he formed his own quintet, with which he explored the deepest roots of Latin American music. Together with musicians such as Cesar Franov, Enrique Norris, Carlos Triolo, Diego Pojomovsky, and Guillermo Bazzola, among others, he made his second recording.

Over the next five years he headed the big band "Los Saxopatas"(1990/95) with which he recorded and performed throughout Argentina. ln Buenos Aires he made the debut of his "solo set show" in which he improvises freely on American folk tunes, interpreting bagualas, vidalas, bailecitos, chacareras and others in his own unique style.
He currently lives in Spain, where he teaches saxophone and improvisation at several music schools and performs both in Madrid and on his own solo tours.
